Recently i cleaned the fuel injectors and the power of the engine is restored, suddenly the engine lost the power and there is a knocking sound coming from inside of the engine. what will be the major cause for this problem?

that pertains to fuel injectors. depends on year.if it has a vortec engine it has spider wire fuel inj.sys.check fuses fuel pump pres. injector pulse.if all ok pull injectors themselves if spraying and clogged
Does the knocking sound increase with engine speed? Check all the things run by the belts, like A/C, alternator, etc. by removing the belts and starting the engine. If there is no more knocking, then check those components. If the knocking is still, you may have an internal engine problem like main or rod bearing failures. Check the engine oil for any metal flakes.
Try changing the fuel filter. If that does not help, have someone test the injector pump for pressure. Last would be a compression test on the cylinders. Drain oil and replace oil filter very soon.
What has happened is the diesel fuel is a lubricant and gasoline is a solvent. As gasoline is much thinner, it could wash down the cylinders and get into the oil pan thinning the oil and ruining the bearings. This would be the reason to test the pressure in the cylinders to find out if you lost compression with the rings in the cylinders.
Next, the injector pump for the diesel has seals and tolerances for inside components. Again, since gasoline is a solvent and not a lubricant, the internal parts could be worn out by not having diesel fuel to lubricate the injector pump parts.
If someone working at the fuel station made this mistake, all the costs should be paid by the station. This is something which could be taken to court if the station does not pay.
HI i HAVE JUST HAD A SIMULAR PROBLEM WITH MY ISUZU 2.5 D MAX EVEN AFTER CLEANING AND REPLASING THE FUEL FILLTER THE ENGINE WOULD CUT DOWN LIKE THERE WAS NO FUEL GETTING THROUGH. PROBLEM SOLVED MY GARAGE MACHANIC TOLD ME TO REMOVE THE TINY FILTER SITUATED IN THE BANGO BOLT WHICH GOES INTO THE INJECTOR PUMP THIS WAS THE PROBLEM AND MY CAR IS NOW RUNNING LIKE A GOOD ONE . DAVE
Most of us know
how the injectors get clogged. Its nothing else but the fuel that we use which
causes clogging. Every time we turn off our car's engine, last drop of petrol dries
on the nozzle of the injector and leaves behind deposits. These deposits become
firm with the heat of the chamber. The more we drive our car, more deposits
accumulate. Gradually it starts to restrict the flow of petrol from the tiny
hole on the nozzle and the injector starts to lose its efficiency. This causes
the engine to lean misfire and hesitate on different rpm, power and pickup is
lost, the car becomes uneconomical on petrol, unburnt fuel can be noticed in
the emission and worst of all the wear of engine becomes faster. Only 8% to 10
% clogging in the nozzle can cause all this
cleaning can restore their like-new performance. There is no need to replace
fuel injectors unless they are actually gone bad. Injectors are designed in
such a way that they are not very convenient to clean. They are sealed units
and cannot be opened for cleaning. Ultrasonic cleaning is MOST effective process for cleaning fuel injectors. It is cheap and
comprehensive solution for the problem.
YOUR FUEL INJECTORS HAS TO BE PRESSURE CLEAN IF YOU HAVE PETROL ENGINE.BEST TO LET GARAGE CLEAN INJECTORS.YOUR POWER LOST PROBLEM COULD BE FAULTY TURBOCHARGER OR WASTEGATE ALSO CHECK FOR RESTRICTED EXHAUST MUFFLER OR CATALYTIC CONVERTER.
the problem is due to your engine temperature sensor which is by fault sense the tempt high, which instruct the fuel injector to give lean fuel ratio to the engine and cause your engine hunting and shut off.on normal condition it sense tempt hi when u already hav enough rich fuel inside your engine thats why it try to reduce your fuel ratio.
I think it sounds like a fuel injection problem. You get fuel for a while until the injector backs up and then all of a sudden NO FUEL. The engine quits and the pressure drops and flow returns enough for you to restart. If I were you I would get to a good mechanic and check the fuel injectors.
OR--try adding a fuel additive that would clean the injectors.--Signed jwr
